A marine ciliate Amphisiella milnei (Kahl, 1932) $Horv{\acute{a}}th$, 1950 was discovered from the tidal pool of Baekdo Island, South Korea. The existence of extra cirri between leftmost frontal cirrus and buccal cirrus discriminates this species from its congeners. Its morphological features are described as follows: body size in vivo $110-130{\times}35-45{\mu}m$; elongate rectangular to elliptical in shape; two large and several small ring-shaped structures; yellowish cortical granules arranged irregularly on ventral side but longitudinally along dorsal kineties on dorsal side; 34-40 adoral membranelles, 3 frontal cirri, 1 buccal cirrus, 1 parabuccal cirrus, usually 2 extra cirri behind leftmost frontal cirrus, and 3 frontoventral cirri; amphisiellid median cirral row composed of 25-31 cirri with 27-36 left and 27-44 right marginal cirri; usually 5 transverse cirri and 2 pretransverse cirri with 7 dorsal kineties; two macronuclear nodules. In addition to, 18S rDNA sequence of A. milnei was analyzed to understand its phylogenetic relationship.

Two stichotrichous ciliates, Amphisiella annulata (Kahl, 1928) and Pseudoamphisiella alveolata (Kahl, 1932), were collected from the Yellow Sea in Incheon, Korea and were identified as new to Korea. The main diagnostic key to the species of the genera are that the two species share the features of two macronuclear nodules, one marginal row per side, and transverse cirri. A. annulata is distinguishable from other members in the genus mainly due to the several ring-shaped (hollow) structures in its cytoplasm and its wide and narrowly arranged amphisiellid median cirral row. P. alveolata has a conspicuous alveolar layer and two conspicuous macronuclear nodules, but no frontoterminal cirri.

Based on morphological observation, we identified nine ciliates previously unrecorded in Korea, Euplotidium itoi Ito, 1958, Anteholosticha verrucosa (Foissner & Schade, 2000) Berger, 2008, Holostichides dumonti Foissner, 2000, Amphisiella australis Blatterer & Foissner, 1988, Terricirra matsusakai Berger & Foissner, 1989, Uroleptoides binucleatus binucleatus Hemberger, 1985, Uroleptoides magnigranulosus (Foissner, 1988) Berger, 2008, Leptopharynx costatus gonohymen Omar & Foissner, 2012, Pseudochilodonopsis mutabilis Foissner, 1981, from three sites in Korea, which were isolated from three environmental samples, consisting of one seawater and two soil samples. These ciliates were assigned to three classes, five orders, five families, and eight genera. In this study, we provide photographs and brief descriptions and remarks of the nine species.

We collected indigenous Korean ciliate species from diverse aquatic and terrestrial habitats in 2018 and 2019. The morphology of these ciliates was revealed based on the observations of living cells, and protargol-impregnated and/or silver carbonate-impregnated specimens. During this study, we found 16 previously unrecorded Korean ciliate species, which are as follows: 1) class Heterotrichea - Stentor introversus; 2) class Spirotrichea - Aspidisca orthopogon, Amphisiella sinica, Epiclintes auricularis rarisetus, Apokeronopsis wrighti, Pseudokeronopsis carnea, Trachelostyla pediculiformis, Strombidium apolatum, and Varistrombidium kielum; 3) class Phyllopharyngea - Chlamydodon obliquus, Dysteria aculeata, and Hartmannula angustipilosa; 4) class Litostomatea - Paraspathidium apofuscum; and 5) class Oligohymenophorea - Frontonia angusta solea, Metanophrys sinensis, and Uronemita binucleata. Here, we provide a diagnosis for each species with a brief remark. Among them, the infraciliature of the poorly known species, Stentor introversus and Dysteria aculeata, is described for the first time. Further, we revise the Korean population of Pseudokeronopsis pararubra, which was previously misidentified as Pseudokeronopsis carnea.
